'SETE` R. AND GEORGE W. BALLARD, OF COLDWATER, "MICHIGAN Letters Patent No. 62,921, dated March 19, 1867. i i I @In Stigchnlc rifatta in in ligue man; @that mit making part nf tige 'samt TO ALL WHOM IT MAY CONCERN:

Be it known that we, SETH R. lBALLARD and GEORGE W. BALLARD, of the city of Coldwater, in the county of Branch, in the State of Michigan, have invented certain new and useful Improvements in n Machine for Carding Wool into a continuous roll for spinning, for domestic purposes, and thel following is a full, clear, and exact description of the same, -reference being 'had to the accompanying drawings, making a. part ei`^this speciiicatiornin whichi Figure 1 represents our improvements in a side view attached to a broken-oli` section of a common'woob carding machine. l

Figure 2 represents an end View of the same apparatus as-attached. y

Figure 3 shows a plan or top view of the mechanism for making continuous rolls.v

Figure 4 shows atop View of the mechanism for moving the guidesl to runlacontinuous roll on to a bobbin.

Figure 5 i's a view of a revolving tube (fullsize) constructed so as to be adjustableto vary the Asize of the rolls in carding diiferent qualities of wool. y

The object of our invention is to produce continuous rolls of carded wool for handspinning in families, for domestic use, thereby greatlyvfacilitating the operation, and making a superior quality of yarn, there being no uneven or weak places, as is the case when spinning the ordinary machine-carded, short rolls, at every place where the rolls are joined together. I

Our invention consists in the construction. of the rotating tubes, they being made with a recess in their. outwardI ends, into which removable conical points, having bores of di'erent sizes, are {itted'and secured with set-screws,rso that by simplyv substituting one of these tips or points for another the size of the ro-11s may be varied inem-ding' to suit the different qualities of wool without removing the rotating tubes or disturbing the belt that drives them, thereby saving much time and delay in carding for customers. Our invention further consists in the arrangement and combination of the mechanism for rotating a series of tubes, and producing the lateral motion to Vthe guides for depositing the continuous rolls on the bobbins so 'that they` can y be safely handled. y

To enable others skilled in the art to make, apply, and use Vour invention, we will proceed to' describe it in detail, referring to the several figures in the drawings, and to the letters of reference marked thereon.

To the platesAA of the frameof a common carding machine, jon the ends which extend out from theA d oiler B, we bolt two pieces of hard wood, C C, of suliicient length to support the table D, on which the revolving tubes-a a a are mounted in their supports b so that any desired number of them can be driven to operate by one belt E E driven by the pulley d. In front of the funnel ends off-'the tubes a is the protecting board F, it being secured to the table D, the board -having smooth round openings through it, corresponding with the funnel ends of the tubes a a a, to admit the slivers after they come off the doffer B. The slivers are slightlytwisted by the revolving tubes while passing through them, and they then pass between the draught rollers c c e e, and also between the guide pins ffff to the bobbins, which rest upon and are revolved by frictional contact with the cylinders 1 I I; the traversing guide mechanism as it moves laterally, delivering the rolls" alternately from end to end of the bobbin as usual. The protecting board F will prevent the rollstin case one of them breaks) from being caught and tangled up by the other rolls as they are entering-,the tube to form the continuous roll The tubes have removable points, l, 7th, that are made separate and provided with sleeves g g, which are fitted into the socket j in the end-of the revolving tube a, and are secured by a set-screw, c, so that the points h L can be easily taken out of the tubes, and others of various-sized openings inserted to produce a roll of any given size, as may be desirable'in carding dilerent qualities of wool. The movable points or sockets h h are made tapering inside, and coneshaped on the outside, so as to bring the p iuts to a sharp edge where it delivers the roll directly between the draught-rollers e e e, thereby retaining the twist.

in the roll, and also dispensing with vibratory condensing rollers heretofore used for the purpose. TheY bobbins on which the continuous roll is wound are placed so as to rest on the rollers 1 I, the bobbin journals being in the bearings iz' z' in the. a-rmsvm m, so as to be filled as they are revolved by the cylindrical rollers I I.

The mechanism which rotates the tubes a a, and gives lateral motion to the guides f ff, is placed upon an independent hase, Gr, Vwith upright posts P P, inwhichpare the bearings of the shaft H, on which is a bevel-gear,

q, to drive the pulleyd, to`rotatlthe tubes a a a of any desired number, by a single belt, F, which passes over the adjustable friction-'roller 7', which operates as a tightencr to the belt as it passes zigzag over one tube and under another alternately for twisting the rolls The guide frame K hasa uniform laterally reciprocating movement for. conveying the rolls on to the bobbins, which is effected by the vertical. piece L secured to the sliding-bar Z, on which is a finger, o, bearing upon the heart-shaped cam Q, which derives its'motion by a pinion, s, 'working in a worm or screw, t, on the end of the horizontal shaft H. Thus it will be seen that there are many and very great advantages in having Wool carded into continuous rolls for hand spinning for domestic use, over the old process of making the short rolls. In the` first place, full one-half'of the time and labor is saved, enabling the operator to produce rtwice Ythe amount of yarn in a given time, and that of a much superior quality, as the bre of the wool is 'all drawn leugthways of the roll giving'it a better texture, greater strength, and more uniformity of size and body than it possibly can have when the rolls have to be spliced together at so short intervals. In the second place, 4the continuous rolls being wound in a compact form on bobbins, they can be handled and transported with much less liablityof being injured by getting stretched or mussed up, than the ordinary short rolls in common use, which haveto be picked out singly and joined together for spinning, and unless the greatest care is taken in making the splice, the yarn spun from the short rolls wili be uneven and have Weak places, which cannotoccur in yarn spun from our improved mode of making continuous rolls and spinning them oit` from the bobbins which are placed in frames which are so constructed that they may be set up in any convenient warm place for spinning in cold weather.

Having thus fully described our invention, what we claim as new and useful, and desire to secure by Letters Patent, is 1 1. The rotating tubes a au having removable tips o rpoints lz, when the same are constructed andV operate as described for the purpose specified. l i

Y 2. W'e claim the arrangement of driving Apulley d, single belt E, friction-roller, belt tightcncr r, and a series, of rotating tubes a a a, in combination with worm-gear s t, heart cam Q. finger o, lever and slide L l for moving thc guide frame K, as described for the purposes-specified.
